This is a penlight sold during the "ARASHI Anniversary Tour 5x20" tour, which celebrated their 20th anniversary. *Batteries not included. I used it at the concert and have stored it with the batteries removed. ◼️Regarding Light Functionality Check: I tested it once when listing it. I will check it again before shipping, once your order is confirmed. The light portion has the design "ARASHI Anniversary Tour 5x20" at an angle, multiple times, with the "5x20" part being larger. You can switch between six colors: white, blue, red, green, yellow, and purple, but it does not blink. It can stand on its own, so you can display it in your room after the concert. The strap is not included. Two AAA batteries are required separately, so please prepare them. Thank you for looking.
